SEAM FORSEWED ARTICLES.

Specification of Letters Patent.

Patented mam-5,1913.

Application filed December 22, 1908. Serial No.'468,850.

To all whom it may concern:

Be it known that I, lViLLI u E. BAILEY, a citizen of the United States, and resident of Beverly, county of Essex, State of Massachusetts, have invented an Improvement in Seams for Sewed Articles, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

This invention relates to a seam for sewed articles designed to be made by machine, and more particularly for use in what is known as padding work wherein two or more superimposed layers of fabric are enter and emergeat the same face of the fabric. Padding work is required, to a -large extent, in the manufacture of mens and womens garments, in securing together and stlifening the various layers of fabrlc.

In this work it is desirable to secure a com-- paratively wide seam that shall bind two or more layers of fabric together firmly without showing on the exposed face of the garment.

These rows of stitches are made close together over considerable surfaces, and hence a 59:11!) which can be made rapidly is desirable. It is also desirable that so far as pos sibl. the seam shall simulate the work hitherto performed by hand. Such seams must also possess a certain amount of elasticity otherwise the work may not lie flat or conform to the shape of the garment without breaking the threads.

The construction of seam of this invention is one which presents perfect elasticity especially in the direction of length of the seam where it is most desired; one in which the appearance of the seam is similar in appearance to the work done by hand; one which may be rapidly performed by machine operation; one in which the layers of the fabric are firmly united at regular and symmetrical intervals; and one in which two threads are employed so that it is adapted to be made upon the lock stitch type of machine. These and other advantages reside in the construction illustrated, and in will be particularly ointed out in the claim.

The drawings ilustrate the preferred form of the seam as adapted to be made by a machine provided with a curved needle, a complemental thread carrying stitch-forming mechanism and a means for securing a vibration of the work support and the stitch-forming mechanism laterally with respect to each other and transversely of the line of scam or feed of the goods.

In the drawings, Figure 1 is a perspective view of the seam. Fig. 2-is a cross-section to show the position of the thread.

The seam herein illustrated is one de signed to be made by a blind stitch sewing machine comprising a needle carrying a thread and a thread carrying looper 00- operating therewith to interlock its thread with theloop of thread thrown out by the needle. Preferably the material is fed over a flat work support and the needle is a curved one so that ateach stroke ofthe nee die it will enter and emerge on the upper face of the fabric and throw o'ut its loop to be passed through by the thread carrying looper, such for example as the rotary hook and inclosed bobbin case. A means is also provided for giving. a ve|ative shogging movement, or relative late al displacement, transversely to the line of feed of the stitchforming mechanism and the Work support.

Preferably the work support remains stationary and the lateral movement is given the stitch-forming mechanism bodily. Since the subject matter of this invention resides per face o-f'the fabric in a zig zag line run-1 ning in the direction of the line of scam or feed of the goods, except at the bends or as uniting two superim-' angles of the zigzag line where it is formed into loops E. These loops E lie transversely of and preferably at right anglesto'the general line of the seam or feed of the goods,

and they enter the upper surface of the fabric at the bend or angles of the zig zag lines, pass into the lower layer and emerge again at the .upper surface.

The looper or interlockin thread is indicated at F and. lso lies on the upper surface of the fabric in a zig za line running allel to the needle three I) and at a s ort distance therefrom and consequently also extends in the line of seam or in the direction of the feed of the goods. This looper thread F passes through eachof the loops E and forms with said loops stitches. The looking or engaging point of the looper thread F with the loops E is located either at the uppersurface of the upper layer of fabric as shown at the left hand end of Fig. l or beneath the upper surface as shown at the right hand end of Fig. 1, depending upon the tension which is placed upon the needle thread to draw the interlocking point back into the goods. It will thus be seen that the stitches, or that portion of the thread embedded in the fabric, extends transversely of the line of seam, enter and emerge from the same or upper face of the fabric, and lie staggered in two parallel rows while the threads which show upon the upper face of the fabric, viz: the needle and looper threads, extend in zig zag parallel lines a short distance apart in the genera] direction of the line of seam. This construction secures great elasticity in the direction incense.

what I claim as new and desire to secure lay Letters Patentis seam for sewed articles comprising a plurality of superimposed layers of fabric, two threads lying upon one face of the fabric in parallel zigzag courses, the said threads being interlocked at intervals, one or both of said threads being formed into loops at the interlocking points and the said loops extending transversely of the line of seam and entering and emerging from the same face of the fabric upon which the par allel threads lie.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
